Linda Marie Law, 55, of Pierre, South Dakota, was last seen at her workplace in Pierre on August 16, 2002. According to case records, she became upset while at work that day and left; she has not been seen or heard from since. Her employer attempted to report her missing when she failed to return to work but was initially unable to file a report, and an official missing-person report was not made until 2007. Law did not keep in close contact with her family, but she had a pattern of calling on holidays and special occasions; her family received no further contact from her after 2002. She is described as a loner who had lived at various points in Illinois, Alaska, Washington, Montana, Arizona, New Mexico, Colorado, Wisconsin, and California prior to her disappearance. Law did not own a vehicle at the time she went missing. She left her Pierre apartment clean and in order, with no signs of disturbance reported.
The case is investigated by the South Dakota Division of Criminal Investigation, with the Pierre Police Department listed as the local reporting agency (South Dakota DCI case number 0703592; NCIC number M167023732). Law suffers from bipolar disorder and requires medication to manage the condition; it is not known whether she had access to her medication at the time she disappeared. Because of this medical history, her case is classified as Endangered Missing. No suspects, persons of interest, or vehicles have been publicly documented in connection with her disappearance. As of this entry, Law remains missing and her case remains open. Anyone with information is asked to contact the South Dakota Division of Criminal Investigation at 605-773-7344 or the Pierre Police Department at 605-773-7410.
